me to be more precise, than that which has hitherto been 
employed to distinguish insects from worms.” 
Ginelin, in his edition of the Systema Naturae, necessarily 
much augmented the number of genera, by collecting all that 
had been established since the last edition of Linnams ; but he 
made no gieat changes in the methodical distribution of 
" orms, except by adding the last class proposed by Muller, 
under the name of infusoria. The chetopoda, and indeed 
all the red-blooded worms were still scattered through the 
three orders of intestina, mollusca, and testacea. He did not 
profit by the observations of Pallas, of Muller, or of Blumen- 
bach. 
In 1789* the part of the French Encyclopaedia* on worms, 
by Biuguieies, made its appearance, with a table of the metho- 
dical distribution of those animals. But this writer, though 
he felt the necessity of establishing a new order, that of 
echinodermata (now in the zoophytes), effected no sensible 
amelioration. Nevertheless, in proportion as the study of 
the animals of the inferior class proceeded, the name of 
i ermes, gi\ en to his last class by .Lin mens, was reserved for 
the animals which the ancients thus distinguished, and ceased 
to be generally employed for the other orders, which were 
named mollusca, testacea, zoophytes, and infusoria. Thus, 
in the Synopsis of Animals, published by Baron Cuvier, in 
1798, the seventh book treats of insects and worms. Under 
the name of worms, he then divided these animals into two 
sections, according as they were provided, or unprovided, 
with setas or spines for locomotion ; or, in other words, into 
chetopoda and apoda, as has been done by M. de Blain- 
ville. Among the first were grouped the species which live 
in tubes, and also the lumbrici ; in the second were placed the 
leeches, and intestinal worms. Thus the observation of Pallas 
was appreciated, and put into execution, by Cuvier, respect-
